Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical systems face challenges in effectively managing excess gas with anesthetic components from anesthesia apparatuses, leading to potential health risks and environmental pollution due to inadequate gas absorption and filtration.
Innovation Solution
A taking up/receiving system comprising a feed line, discharge line, filter unit, and buffer storage device that connects to medical apparatuses to filter out anesthetics and manage excess gas, ensuring it is not released into the surrounding area, with features like detachable connections, filter mounts, and buffer storage to handle varying gas flows and filter replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter unit is added to the taking up/receiving system, then the filtering performance is improved, but the device complexity increases
Solution Approach 1:
The filter unit is designed as a separate, detachable component that can be independently installed and removed from the taking up/receiving system. This segmentation allows the filtering function to be optimized without permanently increasing the complexity of the main system, as the filter can be replaced when saturated.
Solution Approach 2:
The filter unit acts as an intermediary component between the gas discharge line and the surrounding environment. It introduces a new element (the filter) that mediates the interaction between the excess gas and the external environment, improving safety without requiring fundamental changes to the core system architecture.
2Reliability
If a buffer storage device is added to handle varying gas flows, then the system reliability is improved, but the device complexity increases
Solution Approach 1:
The buffer storage device is positioned in the gas flow path to temporarily store excess gas before it reaches the filter unit or discharge point. This beforehand cushioning prevents pressure spikes and flow variations from affecting the filtering process, ensuring reliable operation during varying gas flow conditions without requiring complex control mechanisms.
3Ease of operation
If detachable connections are implemented for feed line and discharge line, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The feed line and discharge line are designed with detachable connections, segmenting the gas flow path into separable components. This allows for easy installation, removal, and maintenance of the taking up/receiving system without requiring permanent welding or complex assembly procedures, despite the added complexity of connection interfaces.
4Object-affected harmful factors
If the filter unit is designed to filter at least one predefined gas component, then the harmful factors are reduced, but the device complexity increases
Solution Approach 1:
The filter unit is specifically designed with filtering properties tailored to target predefined gas components (such as anesthetics) within the excess gas stream. By localizing the filtering function to a dedicated component with specific material properties, the system effectively reduces harmful factors without requiring the entire taking up/receiving system to be complex.

AI summary
A taking up/receiving system (100) and a process for taking up/receiving of gas from a medical apparatus (1) are provided. The taking up/receiving system includes a feed line (6), a discharge line (8), a filter unit (4) with a filter and at least one buffer storage device. The feed line establishes a fluid connection between the medical apparatus and the filter unit. The discharge line establishes a fluid connection between the filter unit and a fluid taking up/receiving unit (7). The gas is discharged from the medical apparatus and is passed through the feed line to the filter unit and from there through the discharge line to the fluid taking up/receiving unit. The filter filters at least one gas component out of the gas that is passed through the filter unit. The one or more buffer storage device absorbs and again discharges gas from time to time.
